Dan Brown’s new novel, the eagerly awaited follow-up to his #1 international phenomenon, The Da Vinci Code, which was the bestselling hardcover adult novel of all time, will be available today (September 15, 2009).

The Lost Symbol will once again feature Dan Brown’s unforgettable protagonist, Robert Langdon.

“The Lost Symbol is a brilliant and compelling thriller. Dan Brown’s prodigious talent for storytelling, infused with history, codes and intrigue, is on full display in this new book. This is one of the most anticipated publications in recent history, and it was well worth the wait,” said Sonny Mehta, Chairman and Editor in Chief of the Knopf Doubleday Publishing Group.
